4.1.7.1.12.1 Reference SweptSolid Geometry
The Reference SweptSolid Geometry is the reference representation of the 3D shape of a product by swept solid models, only allowing for the basic extruded area solids and revolved area solids. Being a reference representation it is normally not displayed and it is not used in a voiding relationship.
The following attribute values for the IfcShapeRepresentation
The following diagram shows the generic classes and relationships used when applying this concept.
In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the table below shows a recommended list of general usage patterns that users may adopt.
